BACKGROUND: The posterior cerebral artery (PCA) is involved in approximately 30% of moyamoya disease (MMD) cases. However, there have been insufficient reports describing revascularization techniques in the posterior portion of the brain, particularly of direct anastomosis. OBJECTIVE: To perform a technical assessment in patients with MMD who underwent either occipital artery (OA)-PCA bypass or OA-middle cerebral artery (MCA) bypass. METHODS: A total of 428 revascularization procedures in 368 patients were retrospectively assessed by reviewing clinical charts and radiological data...

Hepatocellular carcinoma (HCC) is prone to recurrence following curative treatment. The purpose of the present study was to identify the predisposing factors of HCC recurrence following complete remission achieved by transarterial chemoembolization (TACE). A retrospective cohort study of 70 consecutive patients with HCC who underwent TACE as the initial treatment was conducted. The patients were divided into two groups according to their 1-year disease-free survival (DFS) status; the early recurrence group (ER group; n=32), with HCC recurring within 1 year of initial TACE; and the non-early recurrence group (NER group; n=38), who did not experience recurrence within 1 year...

BACKGROUND: Pulmonary arterial hypertension is often associated with connective tissue disease. Although there are some animal models of pulmonary hypertension, an autoimmune disease-based model has not yet been reported. MRL/lpr mice, which have hypergammaglobulinemia, produce various autoimmune antibodies, and develop vasculitis and nephritis spontaneously. However, little is known about pulmonary circulation in these mice. In the present study, we examined the pulmonary arterial pressure in MRL/lpr mice...

BACKGROUND: The early impact of renal transplantation on subclinical cardiovascular measures in pediatric patients has not been widely investigated. This analysis is performed for pediatric patients participating in the prospective 4C study and focuses on the early effects of RRT modality on cardiovascular comorbidity in patients receiving a preemptive transplant or started on dialysis. METHODS: We compared measures indicating subclinical cardiovascular organ damage (aortal pulse wave velocity, carotid intima media thickness, left ventricular mass index) and evaluated cardiovascular risk factors in 166 pediatric patients before and 6 to 18 months after start of RRT (n=76 transplantation, n=90 dialysis)...

Invasive coronary angiography (ICA) with measurement of fractional flow reserve (FFR) by means of a pressure wire technique is the established reference standard for the functional assessment of coronary artery disease (CAD) ( 1 , 2 ). Coronary computed tomographic (CT) angiography has emerged as a noninvasive method for direct assessment of CAD and plaque characterization with high diagnostic accuracy compared with ICA ( 3 , 4 ). However, the solely anatomic assessment provided with both coronary CT angiography and ICA has poor discriminatory power for ischemia-inducing lesions...

Background Ultrasound imaging is able to quantify carotid arterial wall structure for the assessment of cerebral and cardiovascular disease risks. We describe a protocol and quality assurance process to enable carotid imaging at large scale that has been developed for the UK Biobank Imaging Enhancement Study of 100,000 individuals. Design An imaging protocol was developed to allow measurement of carotid intima-media thickness from the far wall of both common carotid arteries. Six quality assurance criteria were defined and a web-based interface (Intelligent Ultrasound) was developed to facilitate rapid assessment of images against each criterion...

Atrial fibrillation (AF) is the most common cardiac arrhythmia that occurs because of several different risk factors, e.g., valvular heart disease, coronary artery disease, age ≥75 years, hypertension and diabetes mellitus. One key risk factor that results in AF, is oxidative stress. Evidence suggests that there is a correlation between oxidative processes and the genesis of AF. Oxidative stress occurs when the generation of reactive oxygen species (ROS) increase due to excessive activity of enzymes including NADPH oxidase (NOX) and xanthine oxidase; or its degradation decrease by dysfunctional antioxidant enzyme systems, such as superoxide dismutase (SOD), catalase and glutathione peroxidase (GPx)...

Pleuritic chest pain is characterized by sudden and intense sharp, stabbing, or burning pain in the chest when inhaling and exhaling. Pulmonary embolism is the most common serious cause, found in 5% to 21% of patients who present to an emergency department with pleuritic chest pain. A validated clinical decision rule for pulmonary embolism should be employed to guide the use of additional tests such as d-dimer assays, ventilation-perfusion scans, or computed tomography angiography. Myocardial infarction, pericarditis, aortic dissection, pneumonia, and pneumothorax are other serious causes that should be ruled out using history and physical examination, electrocardiography, troponin assays, and chest radiography before another diagnosis is made...

Exercise stress testing is a validated diagnostic test for coronary artery disease in symptomatic patients, and is used in the evaluation of patients with known cardiac disease. Testing of asymptomatic patients is generally not indicated. It may be performed in select deconditioned adults before starting a vigorous exercise program, but no studies have compared outcomes from preexercise testing vs. encouraging light exercise with gradual increases in exertion. Preoperative exercise stress testing is helpful for risk stratification in patients undergoing vascular surgery or who have active cardiac symptoms before undergoing nonemergent noncardiac surgery...

Depending on the adequacy of collateral sources of blood flow, arterial stenosis or occlusion may lead to reduced perfusion pressure and ultimately reduced blood flow in the distal territory supplied by that vessel. There are two well-defined compensatory mechanisms to reduced pressure or flow - autoregulatory vasodilation and increased oxygen extraction fraction. Other changes, such as metabolic downregulation, are likely. The positive identification of autoregulatory vasodilation and increased oxygen extraction fraction in humans is an established risk factor for future ischemic stroke in some disease states such as atherosclerotic carotid stenosis and occlusion...

The risk of cardiac or lung failure after liver transplantation (LT) is significant. In rare cases, the usual intensive care techniques fail to maintain organ oxygenation with a risk of multiorgan dysfunction. Although extracorporeal membrane oxygenation (ECMO) is a difficult and risky procedure, it can be proposed as life-saving. Four children with either acute pulmonary (three) or cardiac (one) failure after LT, and the criteria that decided the use of ECMO (level of ventilation and results, dosage of inotropic drugs, cardiac ultrasound, blood lactate) were retrospectively reported...

INTRODUCTION:  The over-the-scope-clip (OTSC) can potentially overcome limitations of standard clips and achieve more efficient and reliable hemostasis. Data on OTSC use for non-variceal upper gastrointestinal bleeding (NVUGIB) in patients with cardiovascular comorbidities are currently limited. PATIENTS AND METHODS:  We prospectively collected and retrospectively analyzed our database from February 2009 to September 2015 from all patients who underwent emergency endoscopy for high-risk NVUGIB in 2 academic centers and were treated with OTSC as first-line (n = 81) or second-line therapy (n = 19)...

Coronary artery anomalies may cause life-threatening cardiac complications; however, developmental mechanisms underpinning coronary artery formation remain ill-defined. Here we identify an angiogenic cell population for coronary artery formation in mice. Regulated by a DLL4/NOTCH1/VEGFA/VEGFR2 signaling axis, these angiogenic cells generate mature coronary arteries. The NOTCH modulator POFUT1 critically regulates this signaling axis. POFUT1 inactivation disrupts signaling events and results in excessive angiogenic cell proliferation and plexus formation, leading to anomalous coronary arteries, myocardial infarction and heart failure...
